Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.
[0025] Please refer to Figure 1 , the present utility model provides a technical solution: a tobacco dry distillation device with adjustable continuous feeding temperature, which includes a dry distillation chamber housing 1, a feeding hopper 2, a carrier gas inlet 3, a material propulsion screw main shaft 4, a discharge bin 5, a gravity steel plate 6, a carrier gas outlet 7, a heating layer 8, a heat preservation layer 9, an observation window 10 and an exhaust pipe 11. For the dry distillation chamber housing 1, a feeding hopper 2 is installed through the upper surface at one end thereof. A carrier gas inlet 3 is installed on the side surface of the dry distillation chamber housing 1 facing the feeding hopper 2. A material propulsion screw main shaft 4 is rotatably connected inside the dry distillation chamber housing 1. The rotating shaft of the material propulsion screw main shaft 4 penetrates the side surface of the dry distillation chamber housing 1, and the rotating shaft of the material propulsion screw main shaft 4 is connected to the output end of the motor through belt drive. The dry distillation chamber housing 1, the feeding hopper 2, the carrier gas inlet 3, the discharge bin 5 and the carrier gas outlet 7 in this device are all made of 304 stainless steel, and the observation window 10 in this device is made of high-temperature resistant laminated glass.
[0026] A discharge bin 5 is arranged on the lower surface of the dry distillation chamber housing 1 away from the feeding hopper 2. A gravity steel plate 6 is arranged between the dry distillation chamber housing 1 and the discharge bin 5. The dry distillation chamber housing 1 is sequentially provided with a heating layer 8 and a heat preservation layer 9 from the inside to the outside. The inside of the heating layer 8 is composed of a resistance wire and a heating guide piece, and the outside of the heating layer 8 is a stainless steel shell. The heat preservation layer 9 is a heat preservation cotton layer. When this device works, the raw material is introduced into the inside of the dry distillation chamber housing 1 through the feeding hopper 2. The raw material in the dry distillation chamber housing 1 is continuously pushed forward by the material propulsion screw main shaft 4, and at the same time, the raw material is heated by the heating layer 8.
[0027] A carrier gas outlet 7 is installed on the upper surface of the dry distillation chamber housing 1 facing the discharge bin 5. There are 2 observation windows 10 arranged on the top of the dry distillation chamber housing 1.

A temperature sensor probe corresponding to the position of the heating layer 8 is arranged inside the dry distillation chamber housing 1. The heating layer 8 is of a three-section structure, and the 2 observation windows 10 are respectively located between the three heating layers 8. During the period when the raw material is heated and pushed, a mixed gas of nitrogen or air is added through the carrier gas inlet 3, so that the hot steam is discharged through the carrier gas outlet 7.

[0029] Working principle: When using this continuously fed and temperature-adjustable tobacco pyrolysis device, raw materials are introduced through the feeding hopper 2, then the raw materials are heated by the heating layer 8, and heat insulation is achieved through the heat insulation layer 9. The material propelling spiral main shaft 4 continuously pushes the raw materials to move, improving the uniformity of heat absorption of the raw materials while transporting them. The two observation windows 10 facilitate convenient observation. Mixed gas is added through the carrier gas inlet 3, and the gravity steel plate 6 automatically discharges the materials into the discharge bin 5 according to the weight of the raw materials. The carrier gas outlet 7 introduces the gas generated during processing from the exhaust pipe 11 into the subsequent treatment process, increasing the overall practicality.
